Natsuki accompanies Atri who is on her way to school. However, when they arrive, they find that most of the school is underwater. Although they managed to get into the school building, inside it was full of empty classrooms and an unexpected teacher. There, Natsuki is faced with the saddening reality of the lives of the people who remained in their town.
Cause our homes got 
swallowed up by the ocean.
لأنّ منازلنا ابتلعها المُحيط
Unsere Häuser sind
im Meer untergegangen.
Nuestras casas se hundieron.
Nuestras casas se hundieron.
La mer a englouti nos maisons.
Le nostre case sono finite sott'acqua.
Porque as nossas casas
afundaram no mar.
Старый дом утонул в море.
